Abstract Introduction Black (B) patients with Mycosis fungoides and Sézary Syndrome (MF/SS) have inferior survival and distinct clinical presentations, including many high risk features compared to non-black (NB) patients with MF/SS in large registry studies from the United States. We sought to characterize clinical differences in presentation, treatment, and outcomes to identify drivers of disparities among B patients with MF/SS. Methods We performed a retrospective review of 417 patients with MF/SS diagnosed between 1990 and 2020 at 6 academic institutions in the United States that serve populations with large numbers of Blacks and minorities. Patients with pathologic review and a confirmed histopathologic diagnosis of MF or SS with a stage >1B as their highest TNMB stage were eligible for inclusion. The primary objective was to assess differences in clinical characteristics, treatment patterns, and survival between B and NB patients. Clinical variables included demographics, insurance, zip code, tumor characteristics, and treatment. Descriptive analysis was performed for each variable. Comparison between B and NB patients utilized ANOVA for numerical covariates and chi-square test or Fisher's exact test for categorical covariates. Kaplan-Meier curves for OS were generated, and subgroups were analyzed separated. Results Among 417 patients, 204 (48.9%) were Blacks, 196 (47.0%) were White, and (4.1%) were other races (8 Asian, 5 unknown, 4 Hispanic). The diagnosis was MF in 366 (87.8%), SS in 47 (11.3%), and other 4 patients. Stage at diagnosis was available for 384 patients. 37 (9.6%) were stage 1A, 165 (43%) were stage 1B, 34 (8.9%) were stage 2A, 58 (15.1%) were stage 2B, 44 (11.5%) were stage 3, and 46 (12%) were stage 4 at diagnosis. The median survival of the whole cohort (n=417) was B patients were younger (median 50.1 years in B vs. 60.5 in NB, p<0.001), more often female (49.5% in B; 35.7% in NB, p=0.004), had higher rates of reported lymphadenopathy (78.5% vs. 70%, p=0.039), longer delays from symptom onset to diagnosis (2.0 years in Black vs. 1.2 years in NB, p=0.014), and higher rates of bacteremia at any time in their disease course (19.7% in Black, vs. 6.6% in NB, P< 0.001) compared to NB patients. There was no difference in insurance status (private, Medicare/Medicaid, or uninsured) or comorbidities by race. There was also no differences in overall TNMB stage at diagnosis (p=0.14) compartment stage, or highest stage (p=0.076). Progression to a higher T, N, M, or B stage occurred at similar frequencies in B and NB patients (n=83 (43.2%) in Black and n=73 (38.8%) in NB, p=0.38). Time to first therapy, time to systemic therapy, or total lines of therapy also did not differ by racial group. A greater fraction of B compared to NB patients received systemic therapy but this did not reach statistical significance (72.6% in Black vs. 62% in NB, p=0.060). There was no difference in large cell transformation at any point, or white blood cell count (WBC), lactate dehydrogenase (LDH), or T-cell receptor (TCR) clonality in skin/blood at diagnosis. On univariate analysis, race was not associated with survival; the median survival was 10.5 years (95% CI 8-13.2) in B patients and 10.9 years (95% CI 7.2-14.1) in NB patients. Covariates associated with inferior survival included older age (p<0.001), number of comorbidities (p< 0.001), bacteremia (p< 0.001), higher overall TNMB stage, higher individual T, N, M and B stage, progression to a higher N or M stage, positive TCR in the blood, WBC value, and LDH value. Insurance status and year of diagnosis (prior to 2010, vs. following 2010) were not associated with survival. On multivariate cox proportional hazard model, age at diagnosis, comorbidities, extra-cutaneous disease, bacteremia, TNMB stage at diagnosis, and progression to a higher nodal stage remained statistically significant for survival. Conclusions We present the first multicenter analysis of racial disparities in MF/SS, with nearly 50% B patients. B patients had distinct presentations, delay in diagnosis, and higher rates of bacteremia compared to NB patients. In contrast to US-registry studies, there was no difference in survival between B and NB patients. This finding could be explained by access to academic centers and/or higher rates of insurance coverage among B patients in our cohort. Additional analyses will be updated at the time of the presentation. Figure 1 Figure 1. Disclosures Allen: ADC Therapeutics: Consultancy; Kyowa Kirin: Consultancy; Secure Bio: Consultancy.

Background and Aim: Mycosis fungoides (MF) is the most common subtype of cutaneous T-cell lymphoma (CTCL) wherein those with advanced stage have a poor prognosis. The objective of this study was to describe clinical characteristics and survival in MF patients who were refractory or had relapsed after a first systemic therapy. Methods: A retrospective chart review study was conducted at 27 sites in Europe. Patients enrolled had a diagnosis of MF and proved to be relapsed/refractory (R/R) prior to 1-Jan-2016 after a first systemic therapy. Overall survival (OS) and progression-free survival (PFS) were estimated from the date of R/R event (defined as the index date) using Kaplan-Meier estimates. PFS was defined as death, progression, second relapse or refractory, or presence of subsequent treatment after index date. Results: This study included 104 advanced R/R MF patients with a median age of 54.5 years (range: 21-82). The median follow-up was 3.5 years (range: 0-20.7) after index date. In total 80% of patients experienced a second R/R, with a median time to second R/R of 15.8 months (range: 0.6-174.6). The median age at death was 65 years (range: 42-85). In total 39 deaths (37.5%) were observed. Among those patients who had a known cause of death (N=35), 18 died of CTCL progression, 11 of CTCL complication or drug toxicity and 7 of other causes. The estimated median OS was 11.5 years (95% CI: 6.5 - not reached). The median PFS was 1.3 years (95% CI: 1.0-2.1). Conclusions: The high rate of R/R and low PFS suggest that the clinical burden of R/R MF is significant in five European countries, and recently approved targeted therapies have the potential of improving outcomes.

Abstract Background Protein C (PC) is a naturally occurring, vitamin-K dependent anticoagulant produced by the liver. Deficiency of PC, which can be congenital or acquired, results in a hypercoagulable state. Patients with severe PC deficiency may manifest severe, often life-threatening, disseminated intravascular coagulation (DIC), purpura fulminans (PF), and/or thromboembolism. Highly purified protein C concentrate prepared from human donor plasma (Ceprotin; Baxter Healthcare Corporation, Westlake Village, CA) is an approved therapy for prevention and treatment of venous thrombosis and PF in patients with severe congenital PC deficiency (SCPCD) in the United States. It is indicated in patients with SCPCD for PF and coumarin-induced skin necrosis, and short-term prophylaxis in the European Union and other countries. Use of protein C concentrate (human) has been reported in patients with acquired PC deficiency. The Ceprotin Treatment Registry is a prospective, international, multi-center, open-label, non-interventional, observational study designed to examine the long-term safety and effectiveness of protein C concentrate (human) in the clinical setting. This is the first large, real-world assessment of the treatment of a rare disease with protein C concentrate (human). Here we report data from the first interim analysis in June 2013 covering a 3-year enrollment period. Methods Patients of any age who received, or were initiating/receiving protein C concentrate are included. The study duration is 5 years (3-year enrollment period plus 2 years of follow-up). All study visits/assessments are in accordance with standard of care, with protein C concentrate dose, dose frequency, duration and route of administration determined by the investigator. The study objectives are to determine the most common medical diagnoses associated with protein C concentrate treatment, protein C concentrate treatment regimens, and safety information based on all serious adverse events (SAEs) and rate of treatment-related AE. Other objectives include: an examination of the relationship between protein C concentrate treatment and outcomes in all registry participants, as well as various subgroups. Descriptive statistical analyses are used. Results At the time of data extraction, 34 patients were enrolled from 26 centers; 10 centers in the United States and 16 centers in Europe. Half of the patients were males. The primary diagnosis of PC deficiency was congenital in 25 patients (73.5%) and acquired in 9 patients (26.5%). The median age at diagnosis was 0.03 years (range 0–19.9). Mean plasma PC activity level was 9% (range 1–40.0). The most common (in ≥3 patients) thrombotic disease-associated conditions were PF (50.0%); blindness (44.1%); thromboembolic disease (41.2%), which included deep vein thrombosis, arterial thrombosis and DIC; stroke (32.4%), and renal dysfunction (8.8%). Of the 23 patients being treated with protein C concentrate, 15 were administered protein C concentrate intravenously, and 8 patients received protein C concentrate subcutaneously. The body weights of patients receiving subcutaneous treatment ranged from 10.0 kg to 57.9 kg. A total of 15 patients received an anticoagulant treatment in addition to protein C concentrate. Eight patients reported 23 SAEs, all of which were considered not related to treatment. Eighteen (52.9%) patients reported 72 AEs; only 1 of them, an episode of upper respiratory infection, was considered possibly treatment-related. In 18 patients in whom PC activity recovery was determined after protein C concentrate treatment, there were no patients documented with poor recovery. Protein C concentrate was used during 18 surgeries/invasive procedures and considered effective in all interventions for which data were available. Conclusions Data from the first interim analysis of the Ceprotin Treatment Registry demonstrate that patients with both congenital and acquired severe PC deficiency who are treated with protein C concentrate (human) have a low incidence of treatment related SAEs and AEs, and treatment with protein C concentrate appears to be effective when used during surgery/invasive procedures. Further patient follow up will shed light onto clinical treatment outcomes.

Abstract Introduction: Essential thrombocythemia (ET) is a chronic myeloproliferative neoplasm characterized by clonal platelet production and an increased risk for thrombotic and hemorrhagic events. Limited real-world data exist regarding the clinical characteristics and treatment patterns of ET in the United States; most prior data have been generated outside the United States. The Myelofibrosis and Essential Thrombocythemia Observational STudy (MOST) is an ongoing observational study being conducted to describe contemporary demographics, burden of disease, clinical management, and patient-reported outcomes in patients with specific risk categories of myelofibrosis (MF) or ET in the United States. This analysis describes the clinical characteristics of patients with ET currently enrolled in MOST. Methods: MOST is a multicenter, noninterventional, prospective, observational study in patients with a clinical diagnosis of specific risk categories of MF or ET (NCT02953704). Eligible patients with ET included high-risk patients (≥ 60 years of age and/or a history of thromboembolic events [TEs]), or low-risk patients currently receiving ET-directed therapy. Key exclusion criteria included participation in blinded investigational drug studies, life expectancy ≤ 6 months, or diagnosis of other malignancy. Data regarding disease and clinical characteristics are collected at usual-care visits over a planned 36-month observation period. Patient demographics and clinical characteristics at enrollment were described with descriptive statistics. Results: At data cutoff (May 18, 2018), 793 eligible patients were enrolled from 85 sites since November 29, 2016. The median age at enrollment was 70 (range, 24-95) years, 66.5% were female, and 89.8% were Caucasian. The median time from ET diagnosis to enrollment was 4.2 (range, 0.0-42.1) years with a proportion of patients diagnosed within 1 year (19.5%), 1 to < 5 years (35.0%), 5 to < 10 years (21.7%), or ≥ 10 years (23.8%) of enrollment. Approximately 40% of patients were retired and 42.7% were working full- or part-time at enrollment. A total of 212 patients (26.7%) had a history of TE at the time of enrollment. The type of TE was available for 148 patients, the most common was arterial events (53.4%); 33.1% had venous, and 13.5% of patients had both arterial and venous events. Six hundred and eighty-eight patients (86.8%) were classified as high-risk. Assessments at the time of ET diagnosis, among evaluable patients, included bone marrow biopsy (51.4%; 393/765) and mutational testing (77.2%; 590/764). Three hundred and forty-nine patients had mutation test results reported at the time of diagnosis; of patients with JAK2 V617F test results reported at the time of diagnosis (n = 313), 78.6% were positive for JAK2 V617F (Table 1). Laboratory values and peripheral blood counts were reported for patients with available data (Table 2). The majority of patients (87.9%) had received at least 1 ET-directed therapy prior to enrollment, which in some cases was the same medication the patient was receiving at the time of enrollment. At the time of enrollment, 740 patients (93.3%) were receiving at least 1 current ET-directed therapy, including HU (71.6%; 530/740), anagrelide (13.1%; 97/740), ruxolitinib (4.7%; 35/740), interferon (3.0%; 22/740), and busulfan (0.3%; 2/740). Of 793 patients, the most frequently occurring relevant comorbid conditions were hypertension (52.7%), history of smoking (44.7%), and hyperlipidemia (24.1%). Among 761 patients with ET-related symptoms assessed at diagnosis, the most common symptoms documented by healthcare providers included constitutional (22.9%), vasomotor (16.0%), and spleen-associated symptoms (3.9%), and pruritus (2.6%). Conclusions: Prior real-world data in ET has predominately been generated outside of the United States or has been reported from single institutional experiences. The MOST study will provide a more complete picture of the patient characteristics and outcomes of patients receiving ET-directed therapy in the United States. Ultimately, these data will be important for determining ET treatment gaps and areas of unmet need.

Abstract Background: Daratumumab (dara) is a human CD38-directed monoclonal antibody indicated for the treatment of patients (pts) with multiple myeloma (MM) who have received ≥3 prior lines of therapy including a proteasome inhibitor (PI) and an immunomodulatory agent (IMID) or who are double-refractory to a PI and an IMID. Accelerated approval was granted in the United States (US) in November 2015, based largely on the results of MMY2002, a pivotal phase 2 study in this pt population. Methods: The objectives of this multicenter, open-label early access treatment protocol (EAP) were to provide early access to dara treatment and collect safety and patient-reported outcome (PRO) data in this pt population. Eligibility criteria were similar to those of pivotal study MMY2002 and included age ≥18 years, documented MM, progression by IMWG criteria following the most recent therapy, ≥3 prior lines of therapy including a PI and an IMID or disease double-refractory to a PI and an IMID, ECOG performance status score 0-2, no known chronic obstructive pulmonary disease or persistent asthma, no ongoing MM therapy, and no prior exposure to anti-CD38 antibody therapy. Pts received dara 16 mg/kg IV weekly for 8 weeks, then every 2 weeks for 16 weeks, and then every 4 weeks until disease progression, unacceptable toxicity, or 60 days after US approval. Pre- and post-infusion medications were administered as in study MMY2002. Serious adverse events (SAEs), grade 3-4 AEs, infusion related reactions (IRRs), and PRO data were collected. Results: In total, 400 pts were screened and 348 pts were enrolled and dosed at 39 US sites from July to November 2015. Median age was 65 (range 27-94) years; 72% were white, and 17% were African American. Three-fourths of pts were symptomatic with an ECOG score of 1 (58%) or 2 (16%). Pts received a median of 8 (range 1-17) doses, and median treatment exposure was 1.9 (range 0.03-6.0) months. Median durations of infusion were 7.4, 4.4, and 3.5 hours for the first, second, and all subsequent infusions, respectively. Half of pts (52%) transitioned to commercial drug after marketing authorization, whereas 37% discontinued due to progressive disease. Treatment emergent grade >3 AEs were reported in 51% of pts. The most common grade ≥3 AEs were thrombocytopenia (15%) and anemia (14%). SAEs occurred in 35% of pts, including 12% of pts with SAEs which were reported by investigators as drug-related. The most common SAEs were infections, which occurred in 11% of pts. Nine percent of pts discontinued therapy due to AEs, including 3% for drug-related AEs. Thirteen (4%) pts had an AE with a fatal outcome, including 2 (0.6%) pts with drug-related AEs (pyrexia, thrombocytopenia/ subdural hematoma). IRRs occurred in 56% of pts, including 8% with grade >3 IRRs. IRRs occurred in 56%, 2%, and 2% of first, second, and all subsequent infusions, respectively; the most common IRRs were respiratory or thoracic symptoms (cough, dyspnea, throat irritation, nasal congestion), which occurred in 31% of pts. The median change from baseline in all the domains of the EQ-5D-5L and EORTC QLQ-C30 scales after 1 and 2 cycles as well as at pts' last assessment was 0, with the exception of EQ-5D-5L VAS, which showed a median increase of 1 and 2 units after 1 and 2 cycles, respectively. Conclusions: EAP results in US pts confirmed the safety profile of dara in MM pts with >3 prior therapies including a PI and IMID or who were refractory to both PI and IMID. SAEs occurred in one-third of pts, but only 12% of pts experienced a drug-related SAE. More than half of pts experienced IRRs, which primarily occurred during the first infusion and were grade 1-2 in severity. Pts maintained their health-related quality of life during a median duration of 2 months of therapy.

Abstract Background: Use of prophylaxis is the evidence-based strategy to prevent joint bleeds and reduce arthropathy for patients with severe hemophilia however, prophylaxis has not been universally adopted in the United States. Amongst patients with severe hemophilia enrolled in the ATHNdataset, the largest database of patients with disorders of hemostasis and thrombosis in the United States, as of 2015, 37% of patients with hemophilia A, and 45% of patients with hemophilia B do not receive prophylaxis. With the approval of extended half-life (EHL) factor products, patients and providers have options for less treatment-intense and burdensome prophylaxis. With the changing landscape of available hemophilia products, we aimed to quantify the number of patients treated at U.S. HTCs on prophylaxis utilizing the ATHNdataset with the objective determining the impact of EHL products on the proportion of patients with severe hemophilia receiving prophylaxis and to characterize use of prophylaxis according to age, race and ethnicity, geographic region, and payer. Methods: The ATHNdataset, a HIPAA compliant limited dataset sponsored by the American Thrombosis and Hemostasis Network (ATHN), was accessed as of June 30, 2018. The proportion of subjects with severe hemophilia on prophylaxis were compared to those on demand by age cohort. The proportion of subjects on prophylaxis was analyzed by race, ethnicity, insurance status, and hemophilia treatment center region. For each group receiving prophylaxis, the product (EHL versus standard half-life (SHL)), dose and frequency of treatment was analyzed. Results: ATHNdataset included 6,160 severe hemophilia patients using factor replacements, 5,234 individuals with hemophilia A and 926 individuals with hemophilia B. Overall, 76.0% (n=4,864) of patients with severe hemophilia are on prophylaxis whereas 24.0% (n=1426) are on demand; this included a total of 76.6% of patients with severe hemophilia A and 72.9% of patients with severe hemophilia B on prophylaxis. Treatment type (prophylaxis or not) had significant associations with age (p-value <0.001), ethnicity (p<0.001), race (p=0.005), hemophilia treatment center (HTC) region (p<0.001), and hemophilia type (p=0.015) (Table 1). Prophylaxis was not significantly correlated with payer (p=0.847) with a similar number of patients with Medicare/Medicaid or private insurance receiving prophylaxis. Among patients on prophylaxis, 30.8% (n=1,462) are prescribed EHL products including 27.4% of patients with hemophilia A and 50.4% with hemophilia B. In terms of dosing frequency (n=758), 73.8% of hemophilia A patients on prophylaxis receive EHL two times per week while 73.7% (n=1,906) receive SHL every other day (Table 2). Of hemophilia B patients using EHL products, 63.3% of patients receive prophylaxis once weekly, 12.7% every 10 days, and 15.0% every 2 weeks (Table 2). Discussion: The ATHNdataset highlights increased use of prophylaxis over the past 3 years in the U.S. with 76.6% of patients with severe hemophilia A and 72.9% of patients with severe hemophilia B currently receiving prophylactic therapy as compared to 63% and 55% of patients, respectively, in 2015. Further, the majority (83.7%) of patients are beginning prophylaxis according to the World Federation of Haemophilia recommendation to initiate prophylaxis by three years of age. There has been an uptake of the use of EHL factor products including a majority of patients (50.4%) with severe hemophilia B. Although not captured in the ATHNdataset, a plausible reason for the increased uptake of EHL in the hemophilia B population includes the data that 91% of patients are able to dose between weekly or less frequently. As the hemophilia treatment landscape continues to evolve, it is important to continue to understand the adoption of these new products into practice and to examine their real-world impact.

The Impact

B ackground Premature death from opioid-related causes imposes an enormous public health burden across the United States. Between 2001 and 2016, the number of opioid-related deaths in the United States increased by 345%, from 9489 to 42 245 deaths (33.3 to 130.7 deaths per million population. Moreover, opioids may have immunosuppressive properties independent of their psychotropic effects; opioid use has been associated with increased invasive pneumococcal disease in a nested case-control study of 1233 Medicaid patients from Tennessee. In liver transplant recipients, opioid use disorder has been associated with increased mortality after transplant. The impact of opioid use disorder on patients receiving blood and marrow transplant (BMT) remains to be defined. Methods We performed a retrospective analysis of all consecutive adult patients who had BMT (autologous and allogeneic) from 1/1/2008 through 1/1/2018 at the James Comprehensive Cancer Center. Overall survival (OS) was measured from the date of transplant to the date of death, censoring at date of last follow up if alive. Progression free survival (PFS) was measured from the date of transplant to the date of disease progression or the date of death, whichever occurred first, censoring at last follow up if no event. OS and PFS were estimated by the Kaplan-Meier method and compared using the log-rank test. Opioid use (OU) was defined as a binary yes/no variable if an opioid was prescribed upon discharge from the hospital after BMT. The impact of OU, along with other patient, disease, and BMT related factors, on PFS/OS, was analyzed using Cox regression method. Results A total of 1585 patients were included in the analysis (Table 1). The median age at BMT was 58 (range=18-79) years; 59% were males; 60% had autologous transplants; and 58% were prescribed opioids upon discharge from the hospital. OU was significantly more in patients who were younger, have had allogeneic transplant, reduced intensity conditioning, had acute myeloid leukemia (AML), or higher BMT comorbidity index (CMI). On univariable analysis, OU was not associated with cumulative incidence of relapse (CIR) or PFS however it was associated with inferior OS; hazard ratio (HR)=1.25, 95% CI: 1.06-1.49; p=0.01 (Figure-1). There were no differences in CIR, PFS, or OS when autologous and allogeneic transplants were analyzed separately. Upon multivariable analysis of OS, OU lost statistical significance after controlling for age, diagnosis, type of transplant, intensity of conditioning regimen, CMI, and disease risk index (DRE). Of interest, OU independently predicted for superior OS at 100 days and 365 days post-BMT; HR=0.29, 95% CI 0.16-0.50 (p=&lt;.0001) and HR=0.47, 95% CI 0.32-0.69 (p&lt;0.001); respectively. Conclusion: Our results suggest that opioid use (OU) may have a long term negative impact on survival in BMT patients. The apparently protective effects of OU early on after BMT is elusive but may be possibly related immunomodulatory effects of opioids. A major limitation of our study is that OU is analyzed at a single time point at hospital discharge after BMT. We plan to undertake a more detailed analysis of ongoing OU after discharge and its impact on survival outcomes after BMT.

Adamts13 Deficiency

Abstract Abstract 2203 Background: Thrombotic thrombocytopenic purpura (TTP) is frequently characterized by severe ADAMTS13 deficiency, the cause of which is unknown. An important exception is ticlopidine-associated TTP (tc-TTP), the most common drug-induced TTP syndrome. In 1998, a possible association of TTP with ticlopidine was reported. In 1999, two additional series reported this association. In 2000, a fourth study reported severe A DAMTS13 deficiency among six of seven tc-TTP persons- suggesting a causal pathway. All of these reports were from the United States. Recently, we reported characteristics of 186 acquired idiopathic (ai)- TTP patients in Japan with severe ADAMTS13 deficiency, noting that clinical and laboratory findings for ai-TTP patients in Japan differed from those for cohorts of ai-TTP patients in Europe and North America- raising concern that TTP findings vary by region of the world. (PLOS One 2011) We now on report clinical and laboratory characteristics of a cohort of TTP patients from Japan with tc-TTP, and compare these findings to three cohorts of tc-TTP in the United States and one cohort of ai-TTP patients from Japan. Methods: We queried a database of thrombotic microangiopathy patients identified from a national TTP referral laboratory in Japan of cases identified between 1998 and 2008. Severe ADAMTS13 deficiency was characterized by activity levels < 5%. All tc-TTP patients and 186 of 911 ai-TTP patients in the database had severe ADAMTS13 deficiency and first onset of TTP. Comparisons were made to tc-TTP patients reported previously from the United States. Results: Characteristics of ai- TTP with severe ADAMTS13 deficiency in Japan and tc-TTP in Japan and US Conclusions: These data from Japan validate insights about tc-TTP initially proposed in 1998, 1999, and 2000 in the United States. Ticlopidine is a likely cause of TTP, the mechanism is via a cross-reactive antibody to ADAMTS13:AC resulting in formation of an ADAMTS13:INH, and therapeutic plasma exchange is necessary for treatment.

Increased Risk

Introduction Pregnancy in sickle cell disease (SCD) is associated with an exacerbation of SCD-related complications and an increased risk of maternal complications. The increased risk is partly due to physiologic adaptations in pregnancy, which include increased metabolic demands and a hypercoagulable state. The maternal death rate for SCD is 629 per 100,000 deliveries, compared to 12 per 100,000 deliveries in black women and 6 per 100,000 deliveries in the general population (Raider et al., 2016). Studies on maternal and perinatal outcomes of patients with SCD present inconsistent and conflicting results. Some studies have reported an increase in maternal complications such as pre-eclampsia, acute chest syndrome and thromboembolic events, while other studies have reported no significant risk in adverse maternal outcomes. The inconsistent findings reported in prior studies may be attributed to small sample sizes and single-centered sites. Our study aims to determine the prevalence and predictors of maternal morbidity among participants enrolled in the SCD Implementation Consortium (SCDIC) registry, which is the largest, most geographically diverse SCD participant sample in the United States. Methods This cross-sectional study included women enrolled in the SCDIC registry who had at least one pregnancy event. The SCDIC is composed of eight academic SCD centers across the United States and one data-coordinating center. Participants were enrolled in the SCDIC registry if they were 18 to 45 years of age and had a confirmed diagnosis of SCD. Enrolled participants completed a series of surveys that collected sociodemographic information, SCD and pregnancy history and data abstractions of participants' medical records was completed. Medical complications queried during pregnancy included: vaso-occlusive episodes, acute chest syndrome, blood transfusion requirement, preeclampsia, maternal diabetes and deep venous thrombosis. Descriptive analysis of sociodemographic, clinical and maternal characteristics was conducted. Bivariate analysis was performed using Chi-Square test, Mann-Whitney U test, t-test, and logistic regressions, as appropriate. A p-value of ≤ 0.05 was considered statistically significant for all analysis. Results The study sample included 743 women who had at least one pregnancy event, and a total of 1066 live births. Almost all women (96.3%) were African American, with a median age of 21 years (inter-quartile range of 19 to 23 years) at first birth. The majority had Hb SS SCD genotype (69.5%; 513 of the 738 with SCD genotype data). Of all reported pregnancies, participants did not use hydroxyurea during conception (78%), and pregnancy (84.5%). Only 2.7 % of the women reported using fertility drugs or assisted reproductive procedures. Seventy five percent of the pregnancies that ended in live births had maternal complications. The leading complications were vaso-occlusive episodes (61.2%), pregnancy requiring blood transfusion(s) (33.2%), preeclampsia (15.4%), deep venous thrombosis (5.6%) and acute chest syndrome (7.7%). When the pregnancies were stratified by SCD genotype, women with Hb SS had a higher occurrence of acute chest syndrome (63.4% vs. 26.7%), transfusion requirement (70.8% vs. 21%) and preeclampsia (66.7% vs 22.4%). In the univariate logistic regressions, multiparous women, with a history of adverse maternal outcomes in a previous pregnancy, had higher odds of vaso-occlusive episodes (OR: 3.42; 95% CI: 2.42-4.94) acute chest syndrome (OR:4.99; 95% CI:2.56- 9.48), transfusion requirement (OR:3.86; 95% CI:2.64- 5.69), and pre-eclampsia (OR:3.36; 95% CI:2.05-5.45). Conclusion In this large multicenter registry, we found pregnant women with SCD have significant maternal complications. Early antenatal care by healthcare providers knowledgeable about risk factors for adverse maternal outcomes in SCD is essential improve maternal and fetal outcomes and reduce the maternal death rate for SCD.

Introduction: With the Federal Drug and Administration approval of the use of emicizumab from birth to adulthood, clinicians will now grapple with when to choose and offer emicizumab for routine prophylaxis, especially in previously untreated patients (PUPs). Given the overall limited real-world reported data and experience using emicizumab in PUPs, we created and administered a survey to medical providers in the United States who care for paediatric patients with haemophilia to investigate real-world practice strategies and treatment selection for PUPs. Methods: After review and endorsement by the Haemostasis and Thrombosis Research Society (HTRS), the survey was electronically distributed by e-mail to all providers included in the HTRS core member list. The survey was also sent to those providers included in a list of Haemophilia Treatment Centre (HTC) physicians (with duplicate emails reconciled). Providers needed to self-identify as ones that treat pediatric patients to be included. The survey was developed as a tiered survey with questions presented to each recipient based on their prior responses. Results: Seventy-seven completed surveys were included and analysed. All participants were active providers at a comprehensive HTC and the majority (93.4%) were practicing at an academically affiliated site. In terms of characteristics of those that answered the survey, forty-eight percent of responders reported that 1-20% of their patients had expressed interest in emicizumab. 46% of participants (34/74) reported that they would personally consider emicizumab as their prophylaxis recommendation for the majority (>50%) of their hemophilia A patients without inhibitors. 57% (44/76) reported that 1-10% of their non-inhibitor hemophilia A patients were already prescribed emicizumab prophylaxis. Each participant was then asked about his or her consideration of emicizumab as prophylaxis therapy for a 2 month old PUP. Just over the majority were unsure or said no to this consideration (51.3%) and their concerns were lack of information on safety and efficacy in this young age group and increased risk for inhibitor development. If the 2 month old PUP had a high risk of inhibitor, the majority of providers who initially were hesitant to start emicizumab prophylaxis would remain so. Of note, those providers went on to be asked if the patient had gone on to complete 50 exposure days without inhibitor development, they would then become more likely to initiate emicizumab prophylaxis therapy. Use of concurrent factor replacement was posed to all participants and there were varied responses. Discussion: Overall, our results reflect a widespread practice variation and a not yet well-standardized or defined approach for the use of emicizumab in PUPs with haemophilia A. In this survey, patient preference and individual bleeding risk were the top reasons for which a provider would consider using switching to emicizumab prophylaxis in both severe and mild/moderate haemophilia A patients. This pattern of practice reflects the current era of individualized medicine. Overall, our findings reinforce the need for more studies to investigate the outcomes of a combined treatment approach with FVIII concentrates and emicizumab focusing in the potential benefit of this approach in decreasing the risk for inhibitor development PUPs. Clinicians also feel the need for further data to help clarifying the safety of emicizumab in this population.
